This confuses me. These aren't necessarily benefits to your service.
If the patient needs an ER visit, you are getting one, however it is initiated.
Community-outreach / in-call? Absolutely. I love that aspect of your service.
Your "A" and "B" benefits seem to be the same, not an either-or. The safer route in A comes from skipping the emergency room in B where applicable and appropriate.
I do like that you cut the waiting time to see an MD, regardless of the situation. Diagnosis is an important first step. But I'm curious about the 'medical kit' provided. Because diagnosis is limited to cases that don't require (for example) lab services, and for non-emergent cases, great. Prescribe the appropriate medication or treatment regime. For anything else, the outcome is likely to be the same - not much is changing in that "golden hour" (with all caveats thereto) in terms of definitive care.
I realize I may be coming across as cynical or skeptical in many of my comments, but I really do wish you success and would be very happy to talk with you further. I'm just raising some of the thoughts and questions that come to my mind as a first responder and, as I'm sure anyone will agree, anything that alleviates pressure on the 911 system is "A Good Thing(TM)".
